In April 1765, he married Albany native Anna
Wendell at the Albany Dutch church. By
1785, nine children were christened in the church where he was a lifelong
member and later a member of the church consistory.

From the mid-1760s, his Rensselaerswyck farm was valued on contemporary assessment rolls. In 1769, he was identified as in possession of the
farm located north of Albany and owned by Stephen Van Rensselaer II. It was scheduled to be transferred to his daughter following the Patroon's death. However, he seems to have held that property for the remainder of his life.

With the outbreak of hostilities in 1775, he supported the crusade for American liberties as an active member of the Rensselaerswyck committee. He stood out by signing the oath of secrecy and the General Association. An experienced officer in the provincial militia, he was commissioned colonel of the Third or Watervliet Regiment of the Albany County militia and saw active duty in the Mohawk Valley, at Saratoga, elsewhere, and against Tories.

After the war, he was approaching fifty and returned to his Watervliet farm. In 1790, his household was served by five slaves.

Obituary: Died, on Friday, June 3, Col. Phillip P. Schuyler, aged 73. He was a vigilant and useful partizan officer
in the revolution, which he advocated as a citizen and soldier with an ardor and sincerity that evinced his attachment to his country. He possessed firmness and fortitude
of mind, as well as sensibility and integrity of
heart. His funeral on Sunday was attended by an unusual
concourse of friends and citizens, to pay the last tribute
of respect to departed worth.
